| cell respiration | the use of oxygen to release the energy in food [the process of releasing energy in a usable form] |
| food chain | series of steps showing the transfer of energy among living things |
| producers | organisms that make their own food [plants are an example] |
| consumers | living things that get energy by eating producers or other consumers |
| decomposers | living things that break down bodies of dead organisms |
| first order consumers | eat only producers |
| second order consumers | eat first order consumers |
| food web | shows the feeding relationships among producers, consumers, and decomposers |
| stomata | pores or openings that control the amount of water in a plant's tissues |
| transpiration | the process in which plants release water through stomata |
| photosynthesis formula | carbon dioxide + water + light energy = glucose + oxygen |
| respiration formula | glucose + oxygen = carbon dioxide + water + energy |
| tropisms | plant responses to conditions in the environment |
| geotropism | roots growing toward the center of the earth |
| phototropism | leaves and stems turn and grow toward light |
| hydrotropism | plant roots grow toward water |
| thigmatropism | plant tendrils curl around almost any object they touch |
| chloroplasts | tiny cell structures that contain chlorophyll |
| glucose | food produced by a plant |
| photosynthesis | process of using light energy to combine carbon dioxide and water to produce glucose |
| starch | extra glucose that plants store |
